Get important insights

Protect your lips!

QuantiForce Brass is the ultimate tool to gather objective and individual insights in brass playing. Measure lip pressure at the mouthpiece with unprecedented precision and combine it with sound pressure level measurements that capture even your loudest tone. See all data in real time for an immediate feedback on your playing or record the data for comparison with other players or later analysis.

Raise your playing awareness with ease - at home, in class and even on stage!

Teaching and learning

A powerful tool for both

With QuantiForce Brass applying the appropriate force is made easy. Both teachers and students have a powerful tool at hand to see the actual lip force while playing, which was never that easy before. Several visualizations help to understand the force applied in different playing situations and in relation to loudness or played notes. And - to make it even more useful - visual alerts can be adjusted individually with your fingertips.

With this supportive tool inappropriate lip pressure is recognized immediately or even avoided in advance. Explore new and exciting ways of teaching and learning with QuantiForce Brass by Bonsai Systems!
